Form 4 is a blazing fast masked SLA (MSLA) resin 3D printer that combines an industry-leading materials library with a reliable, accurate print engine. Powered by Formlabs' Low Force Display™ (LFD) technology, Form 4 completes most prints in under two hours — and print time stays about the same whether you're printing one part or a full build platform of many. Turn your ideas into reality faster than ever with easy workflows, leading reliability, and stunning part quality.

The Formlabs Form 4 Complete Package includes the following items:
Form 4's Backlight Unit generates a uniform area projection of ultra-high-power light using 60 LEDs and collimating lenses, curing an entire layer at once. Combined with a low-force release texture, a flexible-film resin tank, and high-speed automatic resin handling, Form 4 prints up to 5× faster than Form 3+ — and its print time barely changes as you add parts to the build platform.

Form 4 delivers the sharpest details, smoothest surfaces, and most accurate assemblies of any Formlabs printer to date — rivaling injection molded parts.
Form 4 supports 23 Formlabs resins — rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic, and castable — with new materials in development. Open Material Mode (included in the Form 4 Premium Package, or sold separately) unlocks third-party 405 nm photopolymer resins for even more flexibility.

Form 4 was measured to have a 98.7% print success rate by an independent global leader in product testing. Six upgraded sensors precisely control resin temperature, resin level, print forces, and print status, and every printer is factory calibrated so you get consistent results from the first print.


Form 4 works seamlessly with Form Wash and Form Cure to automate post-processing. Form Wash agitates parts in IPA or Formlabs Resin Washing Solution to remove uncured resin, and Form Cure delivers precise, heated UV post-curing so parts reach their final mechanical properties.

Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
